Media/it may concern: a known that I, FREDnRIcK Eecn, a

citizen ofthe United States, residing at Bridgeport, in.. the county of Fairfield and Stateof Connecticut, have invented certain new and useful Improvements in Ldose-Leaf Binders and. I do hereby declare the following tofbea 1111; clear, and exact description of the invention, A such as will enable others skilled intheart to which it appertains to he use the same.

n A nsists of certain arrangements of arts; ceinbinations of parts, such as will "e hereinafter fully described and then parpointed out in the claims which conclude itln H vsf'application. The object of my invention is-to do away entirelyzwith soldering or brazing and to provideadevice: which can be assembled or put together without the aid of any special tools,

whilea'tthe same timethe construction'shall be exceedingly durable.

In the accompanying drawings, Figure 1 is a plan view of my preferred construction; Fig, 2; a cross section with the arched arms closed; Fig. 3,- a view similar to Fi 2, but

showing the arched arms opened-to t eir fulli l-est extent; Fig. 4, a view 'similar to Fig. 3, but

showing thearched arms only part way open; Fig-55, a-horizontal section; and Figs. 6 and 7 VIGWS, similar to Fig. 5 but showing, respectively, different modi ed formsof my im- 2' l provement.

' "lar numbers of reference denote like parts in the several figures of the drawin s.

'Heretofore loose-leaf binders have een constructed in which a pair of rods were confinedwithin the opposite upstanding sides of a resilient retaining late or casing, and oppositelyedis osed arched armshave been pivotedia'roun these res ective rods,' and the lower extremitiesof t 'ese arms have been ivoted together in a plane which normally is below the plane of the side rods; but in this construction it is necessary to employ some sortof stop independent of these rods or arms to limit t e upward throw of the lower extremities of said arms, so that the latter would open uniformly and could not be dis-' arranged. Also .in thisl construct-ion it is necessar that different airs of oppositely-dis pose .arched arms e opened separately,

ention relates to loose-leaf binders;

owing to the fact that these arms are pivoted around the, side rods, or else these arms must whic this loose-leaf binder is connected. In my improvement there is no independent pivoting whatever of the arched arms, but, on the contrary, they are integral with the side rods themselves, which latter have a pivotal or rocking action and the arrangement ,of

one pair of arched arms will effect the opera tion of the remaining pairs of such arms. For a clear understandin of my invention drawings which have been described above.

1 is a casing, preferably made from springably concavo-convex. The sides 2 of this form edges 3, which overhang the bottom of this casing.

Referring to Figs. 1 and 5, wherein my preferred form of construction is illustrated, '4 5 are rods which are disposed in op osite sides of the casing; the extreme ends 0 these rods being formed into complementary arched rods are bent so as to form inwardly-extend" ing lugs 8 9, whose inner faces are cut out, so as to form shallow grooves for the purpose "presently explained. Adjoining these rods 4 5 are rods 12 13 "which arelikewise confined withthe first-mentioned rods. On the outer extremities of these rods 12 13 are formed complementary arched arms 14 15, these rods being bent so as to form inwardly-extending lugs 16' 17 'at the bases of these arched arms, ,while the inner extremities of these rods are simply bent inwardly; so as to form lugs 18 19', that are close to the lugs at the inner ends of the rods4 5. These'lugs 16 17 18 19 all have shallow grooves within their inner faces similar tothe grooves hereinbefore men-'- tioned. The several arched arms pass loosely through openings 20 in the sides of the cas be ow the ledges 3, which extend atthe sides of the casing for the purpose presentl to be explained. '21 is a small wire or-r which is inserted between the various 0 positelydisposed lugs through the groove portions 1 -gll be 0 ened by manipulating, the book to parts is suchthat the manipulation of any attention is called to the ollowin descri f tion, wherein references are ma e to t e steel ,'the bottom of this casing being prefercasin are upstanding and are turned over to I arms "6 7, while at the bases of these arms the.
